In my town, we also have the Red Hat Society. In my opinion, I wouldn't worry too much about it. Go ahead and join, afterall it'll make your mama happy (I'd use it as some major mama-daughter time!) You never know what you might miss out on by passing this chance up to become at least a little bit involved.
